jiggle deformer setting or glitch???

All I'm doing is painting some jiggle weight onto the belly of my model. Translate him and the jiggle works great, rotate him and the jiggle builds momentum off itself slowly snapping back and forth until the wave is blasting his belly 50 feet in all directions.

Instead of jiggling and calming down, the jiggle exponentially increases. What am i doing wrong?
